Abstract:

Aiming at the choice behavior of travelers in multi-mode network connecting dwelling district and urban rail transit stations, the calculation method of the trip time cost in the multi-mode network is improved, which considered the influences of multiple access modes’attraction areas for urban rail transit stations on choice behavior of the travelers. Then a passenger flow assignment model based on Logit-SUE is established and an example is given compared with the existing method. Finally, the influences of the perceptive coefficient to the trip cost θ, the increasing coefficient of trip distance β and the parking distance of shared bicycles l?_bike on the choice probabilities of different access modes are given. Analysis results indicate that when θ is bigger, the choice probabilities of access modes with low costs are bigger. At the same time, with the gradual increase of β, the distance between dwelling district and the urban rail transit station increases, it leads to the decrease of the choice probability of walking mode and the bus access mode has the opposite trend, meanwhile, the choice probability of bicycle mode increases first and then decreases. Finally, the larger the l?_bike, the farther the bicycles are parked, and the choice probability of bicycle mode is reduced, and both the bus mode and the walking mode have the opposite changing trend. And with the increase of l?bike, the influence degree of l?_bike on the choice probability of the bicycle access mode increases first and then decreases.
